I need backup files to a tape drive on a remote server without being prompted for password.
I got the part working to tar files to the remote tape drive like this:

currently I got rsync to work with out being prompted for password like this:

How can I get the above tar command to work like the rsync command so it does not prompt me for a password.
I have set up my samba server. I tested from my windows side, all the public ones works fine except the [homes]. Here is my [homes] setting:
Code:
[homes]
comment = Home Directories
browseable = yes
writable = yes
The homes is suppose to let each user see his/her own home directory. But I tested at the windows side, I found that windows doesn't even prompt me about username or password, it just directly give me "not accessible" error. How do I config so my windows side at least prompt me about username/password?
I've seen how to do this from native linux native server to linux native server. Not a problem. My question has to do with ssh/scp exchange of key exchange between a windows cygwin server and a linux server.There seems to be no /home/root/.. to hold the key exchange files. I've tried this between a cygwin server with a /home/administrator/..subdirectory and the /root subdirectory on the linux server. Is this how I should do this?Someone else set this up between these two servers earlier but forgot to document how it was done in his notes.I don't want to break the existing systems by setting up the key generation incorrectly on the functioning pair's of servers.

From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.
I have a bash script that I am using for doing tape backups. The meat of the bash script is
sudo tar --totals -H pax -cvf /dev/st0 *
This all works just fine.
But of course tape functions have to be ran as root, therefore sudo, requiring the standard user to enter the root password. I would like to be in a situation where the standard user does not need (does not know) the root password. I think my solution is add that standard user.
User named dog to the sudo list.
I have reviewed the sudo man page and looked at [URL]. I am still fuzzy.
1- Will adding user 'dog' to this sudo list do what I expect meaning I can run:
sudo tar --totals -H pax -cvf /dev/st0 *
and the user is not queried for the root password
2- How do I do that? and do I make a cmd alais for only: "tar --totals -H pax -cvf /dev/st0 *"
My distro is OpenSuse.
I am new to using Ubuntu 10.10 that was installed by a friend of mine, but he didn't give me a password for administrator and now when I try to install VLC I am blocked by a password prompt. To make things worse I can't use F1 key, esc key, tab key, 1key (I copy and paste 1 from other pages when I need it). I am at a loss here and all I want is to change the administrator password without validating the current password first.
View 2 Replies View RelatedI have been using an LTO-5 Ultrium-3000 tape drive connected to an ATTO HBA without problem. I can control the tape drive using "mt -f /dev/nst0" and have been able to make successful backups using cpio, tar, and dump/restore. I followed some instructions on the web about how to install the HPE Library and Tape Tools application (version 4.21) which relies on conversion of a rpm to a deb file. The software seems to have been installed correctly and runs. However the hardware scan function does not recognize my tape drive. The following is suggested in the user manual if the tape device is not recognized by the software under Linux:
1. Login as root.
2. Edit the following file:
vi /etc/modules.conf
3. Add the following line as appropriate:
add options scsi_mod max_scsi_luns=128
4. Reboot the computer.
The problem is I don't have an /etc/modules.conf and am not sure exactly which file would be equivalent? If this is even the correct solution.
My tape drive is controllable and functions well using "mt -f /dev/nst0 status" so it seems to be a matter of LT&T software to detect the tape drive.

Does the tar application automatically span tapes or do I need to use switches so it spans multipule tapes? Right now my Full backup will take 2 or 3 tapes.

I'm writing a script which will log into a list of servers if they have public/private keypairs set up. If a server doesn't, I want the script to move on to the next server rather than wait at a password prompt.I'm using OpenSSH version 5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007 on both client and server.I'm using this command: Code: ssh root "at" "IP" -o PasswordAuthentication=no KbdInteractiveAuthentication=no I had to write "at" instead of the symbol, as I'm not allowed to "post URLs to other sites after you have made 15 posts or more."This works for most servers, but not all (on some of them the script halts at a password prompt). I suspect those servers may run an older version of SSH which doesn't support the options I'm providing

Before upgrading to Lenny there was no noticeable delay between entering a username & the prompt for a password when logging in via ssh. Now there is about a 5-second delay which is rather annoying. There is no delay when logging in through the Gnome UI. Anyone know why the delay is there? Is it something about ssh under Lenny? Is there a setting that can be changed?
View 1 Replies View RelatedI made my Fedora 13 box boot up automatically by adding the following to /etc/gdm/custom.conf
Code:
However, when it boots up it prompts me for my password so it can connect to my wireless network (I think it said something about not getting my user password at login). Is there anyway I can get it to remember this?
I would like to make this automatic because this will be a remote box that I will use as a file server, but it wont be turned on all the time. So I'll turn it on when I need it, but I'll need to connect to it remotely, so obviously it needs to be on the network.
Has anyone else encountered the really irritating issue of a hidden WPA network not auto connecting, and prompting for the root password when you manually select 'Connect to hidden wireless network'?
It works fine if I enable broadcasting of SSID but a proviso of my broadband is to keep this disabled. Ubuntu does it without any issue, can't figure out why it won't work on FC14.
So here's the problem. We've got the /etc/sudoers file set up so that users can run commands from /bin like "cat" or "mkdir" without entering a password. The problem is that the "su" command is also in /bin, so if they enter "sudo su", it gives them root access without a password. Here's the /etc/sudoers file:
Defaults targetpw
%users ALL=(ALL) ALL
root ALL=(ALL) ALL
support ALL=(ALL) NOPASSWD: /sbin/, /bin/, /opt/, /etc/init.d/, /elo/
support ALL=(ALL) NOPASSWD: /usr/bin/mysql
Is there a way I can deny /bin/su while still allowing the rest of the /bin commands?
I click on the corresponding checkbox in users and groups but but it doesn't do anything. I also want to disable password prompts in general. Also when I try using Computer Janitor it says it could not complete and to check if other package managers are open, but none are.

we have a server that runs a backup (cron job) at 9:15 every night. When I log on in the morning I have mail message that gives me a long list of all the files that were backed up the night before. For a couple of weeks now, the mail message gives me an empty list. Yet, when I run the same job manually from a #prompt, it runs. I am not able to run this job with cron in the daytime because too many users are in it. I wanted to browse the tape to see if the backup is really failing to copy the files or if they are on the tape and the mail message is bogus.
Since the backkup was done with cpio instead of tar, I'm not sure if I can browse the tape with restore -i anyway.What would be the best way to browse the tape on /dev/rmt/1 without actually restoring anything ?This is an ancient DGUX system, not Linux, and I'm not a unix expert I just inherited this server recently, but a lot of things are very similar to Linux and it looked like this might be a good place to ask.
We have been using an Ultrium LTO-2 tape drive to perform backups of certain information from our file server. Recently, the data that we are backing up has grown too large to fit on the tapes in their 200GB uncompressed capacity. I have been looking around for a way to enable the compression in the drive, but I haven't found much. I am not using any backup software, so I'm not sure if I'll even be able to. I write the tape using a simple 'tar' command, so there aren't a whole lot of options to be set. Is there a way that I can enable the drive's compression, or would I be better off running the tar command with the gzip or bzip flags?

I haven't used tape drives in Linux previously; however I'm trying to figure out how to enable an LTO-4 tape drives built in encryption. Im not that concerned with secure key management, I am looking to just being able to load a key into the drive and get the tape to encrypt. Im for a simple command, but I dont even know where to start. If it varies by device, its an HP Ultrium 4 (1760).
